Influence of Cavity Width on Attenuation Characteristic of Gas Explosion Wave

open access: yesShock and Vibration, 2021
This study aimed to investigate the influence of cavity width on the attenuation characteristic of gas explosion wave. Attenuation mechanism of gas explosion wave through cavity was obtained by numerical simulation.

Diabetes‐Associated Cognitive Impairment: Pathophysiology and Emerging Therapies

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Diabetes‐associated cognitive impairment (DACI) is a common yet underrecognized condition, manifesting along a spectrum from mild cognitive impairment to dementia. DACI encompasses patients who develop vascular dementia (VaD) or Alzheimer's disease (AD) with diabetes as a risk factor; however, in certain patients, particularly those lacking ...

Experimental study and model prediction of acoustic wave dispersion and attenuation in medium-coarse sandy sediments

open access: yesAll Earth
A comparable joint dataset of compressional-wave (P-wave) and shear-wave (S-wave) speed and attenuation for saturated Ottawa sand under consistent sample conditions was obtained, using a dual-probe acoustic measurement method (DPAMM) for P-waves (20–150 ...

Wave Attenuation by Sea Ice in the Arctic Marginal Ice Zone Observed by Spaceborne SAR

open access: yesGeophysical Research Letters, 2023
Attenuation of ocean waves by ice is a crucial process of the interaction between waves and sea ice in marginal ice zone (MIZ), while such interaction can contribute to the retreating of sea ice in the Arctic. Based on the retrieved two‐dimensional ocean

Copine‐4 Paraneoplastic Autoimmune Encephalitis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT We characterize copine‐4 (CPNE4)‐IgG and report clinical associations. Among 844 samples with unclassified neural IgGs identified by mouse‐brain indirect immunofluorescence assay over 2 years, 5 samples (serum, 3; CSF, 2) from 3 patients produced a distinctive cerebrum‐restricted synaptic pattern.

Pore-scale modeling of pore structure effects on P-wave scattering attenuation in dry rocks.

open access: yesPLoS ONE, 2015
Underground rocks usually have complex pore system with a variety of pore types and a wide range of pore size. The effects of pore structure on elastic wave attenuation cannot be neglected.

A paradigm shift in the quantification of wave energy attenuation due to saltmarshes based on their standing biomass

open access: yesScientific Reports, 2022
Most existing analytical and numerical models to quantify wave energy attenuation attributed to saltmarshes are based on the definition of a drag coefficient that varies with vegetation and wave characteristics and requires calibration, i.e., a case ...

Extended plane wave expansion formulation for 1-D viscoelastic phononic crystals

open access: yesPartial Differential Equations in Applied Mathematics, 2023
The extended plane wave expansion (EPWE) method is formulated in order to obtain the complex dispersion diagram of bulk waves in 1-D viscoelastic phononic crystal solids considering the standard linear solid model (SLSM).

Attenuation of gravity waves in fast ice

open access: yesДоклады Академии наук, 2019
The attenuation coefficients of sea waves in ice in the coastal zone of the Sea of Okhotsk with periods from 4 to 30 s were estimated as a function of their wavelength based on observations. We used the model dispersion relation for these waves in ice and calculated the theoretical attenuation coefficients.

Artificial Intelligence in Systemic Sclerosis: Clinical Applications, Challenges, and Future Directions

open access: yesArthritis Care &Research, EarlyView.
Systemic sclerosis (SSc) is a rare autoimmune disease defined by immune dysregulation, vasculopathy, and progressive fibrosis of the skin and internal organs. Despite advances in care, major complications such as interstitial lung disease (ILD) and myocardial involvement remain the leading causes of morbidity and mortality.
